Can Dogs Eat Milk?
The short answer · Milk for dogs
Milk often upsets dogs' stomachs. The ASPCA explains that pets don't make much lactase, the enzyme that digests milk sugar, so milk and other dairy can cause diarrhea or other digestive upset. If you want to offer dairy, a small cube of cheese is gentler — but it isn't necessary.

What to know about milk and dogs
Key points
- Water is all your dog needs to drink.
- If you try dairy, start tiny and stop if you see loose stools.
Risks
- Diarrhea and digestive upset from lactose (ASPCA)
Treats, including people food, should be a small share of your dog's daily calories: the ASPCA and one VCA guide say no more than 5%, and VCA's training guide allows up to 10%. Most of your dog's nutrition should come from a complete and balanced diet.
